Bathymetry

Bathymetric investigations serve the purpose of extracting depth information over large areas using acoustic signals, which are reflected by the ocean floor. The measurements are based on runtime measurements for every measuring beam, which is converted into 3D depth coordinates with the help of information about the local sound velocity and the adjacent position.

The field of bathymetry is split into planar and linear recording of the ocean floor topography, whereby different sensor systems are used.

Multibeam Echosounder

Vermessungsbüro Weigt has various multi-beam systems in its in-house stock, which are used according to the measurement accuracies required and the distances between points.

Singlebeam Echosounder

Linear depth recording is made possible using single beam echo sounding. These systems are predominantly used for surveying rivers and monitoring coastal areas, and especially for recording longitudinal and transverse profiles.
